Resumen

We characterize the sequences (wi)8i=1 of non-negative numbers for which ∞Σi=1aiwi is of the same order as supnnΣi=1aiw1+n-i when (ai)8i=1 runs over all non-increasing sequences of non-negative numbers. As a by-product of our work we settle a problem raised in [1] and prove that Garling sequences spaces have no symmetric basis. © ELEMEN , Zagreb.
